In [[computer science]], '''distributed shared memory''' ('''DSM''') is a form of [[memory architecture]] where physically separated memories can be addressed as a single shared [[address space]]. The term "shared" does not mean that there is a single centralized memory, but that the address space is shared—i.e., the same physical address on two [[Processor (computing)|processors]] refers to the same location in memory.<ref>{{cite book
